The Horsehead and Flame Nebulae

I imaged the Horsehead for the first time in mid November, but was never fully satisfied with the result. I had a lot of internal reflections in my scope that caused the light from Alnitak to bleed far into the image. So I had to keep it out of frame, which also meant I missed out on the Flame Nebula. Before I took this image I spent several nights playing with my scope, trying to track down the source of the poor diffraction pattern. What I ended up doing was masking off the mirror clips and edges of the primary mirror. Doing this lost me a little collecting area, but greatly improved the diffraction pattern and the appearance of bright stars. With that issue finally fixed I gave this object another shot, now including Alnitak and the Flame Nebula!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
